Beceem boosts WiMAX performace

Source: Telecoms December 2, 2009 Written by James Middleton WiMAX chipset vendor Beceem Communications has unveiled a number of uplink performance improvements to its portfolio of 4G chips. The 4G Turbo improvements may appear in any WiMAX network as they work with every Wave 2-compliant WiMAX base station, the company said, enhancing network coverage and user experience, especially at the cell edge and in areas of low signal strength. The improvements provide Dual Antenna Transmit diversity for maximum uplink performance under all signal conditions and deliver a gain of approximately 2dB compared to other WiMAX products, Beceem claims.

Android comes to WiMAX

Source: Telecoms Google-backed mobile operating system Android has been given a boost in the mobile WiMAX space due to a partnership between D2 Technologies, Beceem Communications and ECS. The joint initiative will look at the deployment of the Android operating system on smartphones delivering VoIP over WiMAX and other IP-based communications capabilities. D2 provided its mCUE converged communications client paired with Beceem’s high performance BCSM250 WiMAX modem and deployed on WiMAX-enabled smartphones and MIDs such as the ECS T371. In early November, D2 and Beceem completed what they claim to be the world’s first mobile VoIP calls over WiMAX on Android using the Zoom OMAP34x-II mobile development platform (MDP) and a Beceem BSCM250 WiMAX modem with D2’s kernel-level embedded voice engine.

Improving LTE Uplink Reliability

Cambridge Consultants has launched DUEL (Dual-domain Uplink Equaliser for LTE), a platform that the company says will significantly improve LTE uplink performance when compared to MMSE, the "text-book" receiver design. DUEL, designed as an algorithmic and DSP extension to LTE base station receiver designs, requires no changes to handsets. Cambridge Consultants' patent pending DUEL receiver take advantage of properties of the LTE uplink signal to reconstruct what was transmitted with higher fidelity than a conventional text-book receiver. As a result, it works well even when the signals received by each BS antenna are highly correlated. Read full article...

Almost Two Million Mobile WiMAX Subscribers Expected by End of 2009

Source: Cellular News Over the last several years, mobile WiMAX has moved through standardization, productization, and interoperability testing and certification. Larger-scale network deployments are finally becoming a reality. Clearwire in the United States has already declared 173,000 subscribers, Yota in Russia has been growing at a decent rate reaching 100,000 subscribers in August and 200,000 in October, and PacketOne in Malaysia has reached 130,000 subscribers. UQ Communications once expected to reach 300,000 subscribers by the end of 2009, but is behind schedule in its rollout and will fall short of that initial target. South Korea has seen KT's and SKT's subscriber numbers remain fairly stagnant, while these service providers prepare for another big push as a third WiMAX service provider comes to South Korea. This handful of WiMAX service providers alone will account for a significant minority of the nearly two million mobile WiMAX subscribers expected by the end ...

Telefónica to run LTE trial with Nokia Siemens Networks

Source : NSN Press Nokia Siemens Networks has been selected to participate in a Long Term Evolution (LTE) trial in the Czech Republic, as part of LTE trials that Telefónica will be running in about half a dozen countries in Europe and Latin America. During the six-month trial, Nokia Siemens Networks will demonstrate its end-to-end LTE solution that allows operators to offer a completely new mobile experience to their customers. “We expect this trial with Telefónica to demonstrate the potential for our LTE to deliver an entirely new broadband mobile experience,” said Carlos Reines, head of the corporate Customer Business Team for Telefónica at Nokia Siemens Networks. “We are one of the main partners for Telefónica in the deployment of mobile radio networks around the world.” ”We have a long and successful track record of collaboration in the Czech Republic and have provided 2G and 3G technology for Telefónica CZ,” Reines said. The two companies have also been focusing on LTE dev...

Consumer is driving adoption of technology; learning is over with China’s TD-SCDMA

Source: ZDNET China's TD-LTE standard is unlikely to face the same obstacles that plagued the country's earlier mobile wireless standard, TD-SCDMA, industry analysts say. China in October submitted TD-LTE specifications to the International Telecommunication Union (ITU) for approval as a 4G standard. If ratified, it will be officially recognized by the ITU as a 4G technology in October 2010, according to reports. While the country's 3G predecessor, TD-SCDMA, got off to a bumpy start, dogged by technical issues and a lack of device variety, industry watchers are expecting TD-LTE to fare better. Julian Bright, Informa telecoms and media analyst told ZDNet Asia that TD-LTE, as a variant of FDD-LTE (Frequency Division Duplex LTE), is technically similar to the global LTE standard meant for markets where TDD spectrum is more readily available. As such, "strictly speaking, TD-LTE is not a new 4G standard", he said. In comparison, TD-SCDMA was developed largely for...
